所得再分配에 關한 硏究 : 負의 所得稅를 中心으로 WITH EMPHASIS ON THE NEGATIVE INCOME TAX

鄭柱成 단국대학교 대학원 1989 學術論叢 Vol.13 No.-

The purpose of this paper is to consider a propriety of the negative income tax(NIT) as a positive redistribution policy in korea. NIT as a kind of welfare tax system that combines a social security with tax system is the plan that subsidizes a low income group below the tax exemption limit. And because that NIT can indude all the law income group below the exemption limit and secure a finance resources stably and raise the level of income guarantee and self-support by producing incentive of labor supply, we are able to say that NIT is superior to the existing transfer system. Also in considering that Korea economy have to improve a regressivity of tax burden and a distortion of income distribution, NIT is suitable as a positive redistribution policy. Therefore an introduction of NIT have to be considered positively as an income redistribution mechnism.

Magnetic resonance imaging has been used in the temporomandibular joint(TMJ) primarily to define morphology and positional relationship of associating structures. This report examines signal intensity characteristics of the posterior attachment as they related to the severity of internal derangement. Fifty six joints in 35 patients with a history of TMJ dysfunction were imaged writ MR using $T_1$-weighted spin echo sequence. According to disk position, ability to reduction, and the presence of osteoarthritis, the joints were categorized into three groups. A group 1 was anterior disk displacement with reduction; a group 2 was anterior disk displacement without reduction; a group 3 was anterior disk displacement without reduction and condyle had osteoarthritic change. The control group was determined by the clinical absence of any signs or symptoms of current or past TMJ pain and dysfunction. Calculated the relative value of MR signal intensity in posterior attachment and disk to cerebral cortex of temporal lobe by means of computer program, we have compared them with each groups. The result showed statistically little significant difference of disk signal intensity among each groups. but, signal intensity from posterior attachment in group 2 and 3 were significantly(p<0.05) decreased than control group. this might reflect an fibrosis or hyalinization of posterior attachment, which was part of remodeling process that occurs in disk displacement without reduction. However, this study could not demonstrate histologic confirmation of the decreased signal intensity in the posterior attachment. So, further investigation could be needed to understand the association between them.

The purpose of the present study was to investigate the effect of the composite grafts of calcium sulfate and bioactive glass 45S5 in combination with calcium sulfate barrier in the experimental bone defects. Twenty rabbits, weighing about 2.5kg, were used. Three artificial bone defects, 5×5×5㎣ in size, were made at the mandibular angle area. In the experimental group 1, the bone defect was filled with bioactive glass 45S5 and calcium sulfate; in the experimental group 2, the bone defect was filled with the composite graft of bioactive glass 45S5 and calcium sulfate and covered with calcium sulfate membrane barrier. In the control group, the bone defect was filled with blood and was spontaneously healed. The rabbits were sacrified at 1, 2, 4, 6 and 8 weeks after the operation. Microscopic examination was performed. The results obtained were as follows; In the experimental group 1, prominent new bone formation was observed in compared with the control group. In the experimental group 2, extensive osseous regeneration was demonstrated in compared with the experimental group 1. The bioactive glass 45S5 were minutely cracked at week 2, and connective tissues were migrated into inner portion of the glass particles through the crack at week 4. As a consequence, each glass particles may function as a nucleation-site for new bone formation. As the experimental time elapsed, the amount of new bone formation was increased in the two experimental groups in compared with the control group. These results suggest that the composite graft of bioactive glass 45S5 and calcium sulfate promote new bone formation, and the composite graft in combination with calcium sulfate barrier is considered as a potential method for osseous regeneration.

This study is carried out to analyze transition about educational facilities of elementary schools with the change of policy and to find out a developmental direction for qualitative improvement. An analysis of blueprints is done to 34 elementary schools representing periodic characteristics after the 1960's. As a result, various cases were shown in arrangement type, unit space, block planning and plane planning of the schools after a abolition of law about the standardization of educational facilities on 1997, however, they were showing a tendency to simplify after the introduction of BTL on 2005. Spatial composition factors were very various in the schools planned from the middle of 1990's to the early of 2000's. Meanwhile, nearly fifty percent of occupying ratio about learning space in the schools of standard type was gradually decreased by modernization planning on 1990's. However, it was increased a little again after the BTL. In case of living area, the occupying ratio was comparatively high in the schools having characteristics of 1990's and it also tends to increase after the introduction of BTL.

所得再分配에 관한 硏究 : 公共勤勞福祉 增大方案을 중심으로 WITH EMPHASIS ON THE WELFARE POLICY FOR WORKING FAMILIES

정주성 단국대학교 대학원 1992 學術論叢 Vol.16 No.-

The purpose of this paper is to consider a properiety of the welfare policy for the working families as a positive redistribution policy in Korea. A redistribution function in capitalistic economy is the major part of government function because of the capitalistic economy has not an ability to correct the inequality automatically. Recently an income redistribution policy is emphasized by the working families in Korea. The reason is that the wages of the working families was raised in the last several years but they feel that they are low their real income and econnomic status rather than before on account of a speculation in real estate. So they demand intensively not only a raise in wages but an increase of welfare benefits for the real income rise. From this viewpoint, we can estimate that an expanison policy of working families welfare like 'the working families housing policy' is effective. Now an improvement of income distribution is not a bottleneck of growth but a precondition for growth in korea economy. It is important that we realize that the stabilization of prices and the eradication of speculation in real estate is the efficient redistribution policy.

The purpose of this study is to apprehend preference tendency of teachers based on the consciousness of preference about surplus classrooms occurred on the modernized elementary model schools in Chonnam area, and to pile up basic data for planning of classroom rearrangement. A usability pattern of physical facilities is investigated by interviews of teachers and managers concerned with utilization of surplus classrooms. A preference degree about management of surplus classrooms is analysed by questionnaire of teachers. By the analysis, student public living area ㆍ managemental area for supplement (F1), community learning area (F2), subject learning area (F3) and information area for learning (F4) factors are orderly influential to preference consciousness of teachers, and there is a certain difference of viewpoint with each factor. These results show that the consideration in relation with each factor is inadequate as before, and the long-term and systematic manual for utilization of surplus classrooms is required in the managemental and educational aspects.

This study was carried out to investigate consciousness of users about management of multipurpose space introduced in open planned elementary school after the year of 1990's. Thirteen open planned elementary schools were participated through questionnaire and interviews. As the results, the positive response was maintained a superior position in the need of multipurpose space and changes of classroom management. Independence type in the arrangement of multipurpose space and the additional corridor type having extra moving line in comparison with the extensional corridor type were remarkably preferred, respectively. The consciousness of utilization about multipurpose space was comparatively low in a type having traffic line in surroundings of classroom compared to a type having entrance or a type having roundabout corridor. Finally, the group accepting changes positively showed high need to solve urgent problems about management of classroom.

This study was carried out to observe awareness of students using homebase on variation type, about a thousand students in four middle and high schools participated in questionnaire. By the analysis of questionnaire, degree of awareness regarded homebase as a base was relatively high in respondents of the schools having easy accessibility of the homebase, and thus, proportions of assigned space for homeroom, using frequency of homebase and time to stay were also high in the group showing high awareness about homebase. Especially, it is noticeable use of homebase was frequent in the schools having subdivided space in itself. This result suggested that the function of homebase as a base of the students can be very important factor to plan schools of variation type.
